Film Scanning in Practice: Building Accurate, Scalable Workflows for Transmissive Materials
Digitizing film and other transmissive materials presents a unique set of challenges—extreme resolution requirements, focus precision, color inversion, and the need to balance speed with accuracy.
In this Digital Transitions webinar, Ben Cort, Technical Services Manager at Digital Transitions, walked through a complete, real-world film scanning workflow, demonstrating how to capture high-quality film images efficiently and repeatably.
The session focused on practical techniques for digitizing slides and negatives using DT imaging systems, while highlighting common pitfalls and best practices that can significantly improve outcomes for libraries, archives, museums, and digitization studios.
A Purpose-Built Film Scanning Setup
The webinar began with an overview of the imaging configuration used throughout the demonstration. Ben outlined a camera-based film scanning setup built around a high-resolution Phase One iXH system paired with extension tubes to achieve the necessary magnification for film capture. Film was supported using the DT Film Scanning Kit mounted on a DT Atom, with illumination provided by the DT Photon light source.
This combination allowed for precise control over focus, resolution, and illumination—three critical variables when working with small, detail-dense film formats.
Managing Resolution and Focus at High Magnification
A significant portion of the webinar addressed one of the most challenging aspects of film digitization: achieving and maintaining critical focus at extremely high resolutions.
Ben demonstrated how to establish a target capture resolution—5,000 PPI in this case—and how to physically position the camera to match that resolution when working with extension tubes. Rather than relying solely on lens focusing, the workflow emphasized using the copy stand column to fine-tune camera position, ensuring accurate resolution while maintaining sharp focus across the film plane.
Because film content itself is not always a reliable indicator of focus, the session highlighted the importance of evaluating edges, film borders, sprocket holes, and even dust to confirm true sharpness.
Pre-Flight for Transmissive Materials
Once focus and resolution were established, the workflow transitioned into a transmissive-specific pre-flight process. Ben walked through the key Capture One settings required for accurate film capture, including:
- Capturing in Photography mode, rather than film positive or negative modes
- Using the correct ICC profile for the light source
- Applying a linear scientific curve to preserve highlight detail
- Performing Lens Cast Calibration (LCC) to correct for falloff and extension tube artifacts
Exposure was set based on the brightest part of the illuminated film area, ensuring maximum data capture without clipping—an approach that preserves flexibility during post-processing.
Slides vs. Strip Film: Adapting the Workflow
The webinar demonstrated how the same core setup could be quickly adapted to different film formats. Slides and strip film were loaded using different carriers, requiring minor focus adjustments due to height differences, but without the need to redo the full pre-flight when changes were minimal.
This adaptability is key for scalable film digitization projects, where efficiency depends on minimizing setup changes while maintaining consistency.
Processing Film: Object vs. Content Reproduction
A major takeaway from the session was the importance of distinguishing between object reproduction and content reproduction.
Ben demonstrated a two-variant workflow:
- One variant preserves the film as a physical object, documenting base color, density, and condition.
- A second variant focuses on content reproduction, applying inversion, color correction, and tonal adjustments to reveal image detail.
This approach allows institutions to preserve the physical reality of the film while also producing images optimized for access
and interpretation—a critical consideration for cultural heritage collections.
Efficient Batch Processing for Large Film Collections
The webinar concluded with practical strategies for scaling film processing across large collections. Techniques included:
- Batch cropping and rotation
- White balancing from the film base
- Using auto levels selectively to improve legibility
- Leveraging Capture One’s film negative tools appropriately
By focusing on repeatable adjustments and batch-friendly workflows, the session demonstrated how high-quality film digitization can be both accurate and efficient at scale.
Practical Guidance for Real-World Film Digitization
This webinar offered a clear, field-tested look at modern film scanning workflows—grounded in real equipment, real software, and real production constraints. Rather than presenting a theoretical ideal, the session focused on what actually works when digitizing slides and negatives at high resolution.
For institutions and studios working with film collections, these techniques provide a roadmap for improving quality, consistency, and throughput—while maintaining the care and precision that cultural heritage materials demand.
